More Information

Rexener PR200 Water Heater

This hot tub heats up quickly and easily with its advanced Rexener PR200 water heater. The Rexener PR200 water heater can heat the water from +7 degrees to +38 degrees in less than two hours, with just the press of a button. When the heater is running, its fuel consumption is just 2L/hour. The thermostat will turn the heater off when the water reaches the right temperature, saving on fuel consumption. When the water temperature falls by 2–4 degrees, the heater will turn itself back on to maintain the set temperature.

You can lower the temperature to +10 degrees if the hot tub is not in constant active use. This prevents the water from freezing and helps to save energy.
This water heater can be fuelled using diesel or bio-diesel such as Neste MY and Aspen fuels, among others. It does not generate smoke that might disturb your neighbours. It generates only minimal emissions.

High Quality Fibreglass Pool

The fibreglass inner pool is durable, robust, easy to clean and guaranteed for up to 10 years. It can be filled with fresh water or even sea water.

Mass Filter & Water Circulation Pump

The included mass filter keeps the hot tub water clean for a long time, so you can keep the same water in the hot tub for up to several months without having to keep draining the pool. It comes with the required number of filter fibre balls included. You can use pool chemicals to extend the water replacement interval. If you use pool chemicals, keep the water’s pH within the set limits, i.e. 7.0–7.6.

The Rexener PR200 water heater is so efficient that it requires a high-volume water circulation pump to circulate the water. The capacity of the Rexener water circulation pump is 6,100 l/h.

Inspired By Northern Nature

The colours and material choices used in the crafting of Rexener hot tubs are inspired by northern nature. The pool colours, for example, reflect the building blocks of the dream-like winter landscape – white snow and the black granite stone of the north, Gabro.

Versatile Installation

The Unnukka hot tub must be placed on an even surface that can withstand its total weight when full. (ca. 2,000 kg). The hot tub can be set on a bed of crushed stone, or on a concrete base. It can also be installed or embedded in a terrace.

In choosing the spot for your hot tub, remember to consider where you’ll drain the water. It is possible to direct the water flow elsewhere with a hose. The drainage valve is located on the opposite side of the heater from the barrel and fits a 38mm inner diameter hose.

The Unnukka hot tub can be used in the winter. However, do not allow water to freeze inside the water heater/hot tub/water circulation pump. If you wish, you can keep enough water warm so that it can’t freeze, which means you do not need to drain the pool. If the heater is not in use (or the hot tub is otherwise kept warm), the pool must be drained before temperatures drop below zero.

The fuel will keep in its tank, which means you do not need to drain the fuel tank even in freezing temperatures. We recommend replacing the fuel if it has remained unused for a long time.

Please note: Make sure you use winterised fuel when using the heater in freezing temperatures.

Accessories Available

We have a range of great accessories available for this hot tub, including wooden steps to gain access into the hot tub from the ground, and an insulated cover to protect the pool when not in use and to keep the heat contained inside the pool when it is being warmed up.

Easy Upkeep & Top-Class Support

Rexener hot tubs offer a luxurious addition to your outdoor space. They are designed and built to last. They have been designed to minimise the number of accessories and unnecessary parts, making the hot tub easy to maintain. If you wish, you can maintain your hot tub on your own.
